'LAMP-DINNER.

To' all 'whom it ma 1/ Concern Be 1t known that l. GEORGE ilianapolis,`Marion county, and State of ln- "diana, have invented and discoveredcertain new and "useful lniprovements '1n Lamp-- llinuners, of which thefollowing is a specitieaiion.

My inventionrelatesvto dimmers for automobilel lainps, and its object isto provide a Adevice of this class having means forse l interrupting anddciecting the rays .ofthe tothe lower rays substantially'the fullstrength of the rays above the center of the lamp. i

With this object in view, my invention is embodiedin preferable form inthe device hereinafter described andillustrated in the accompanyingdrawings.

In these drawings, Figure 1, is a front full-size View in elevation ofthe dimming Adevice; Fig'. 2, a side view in elevation thereof, and Fig.3, a reduced vertical section of the lamp showing thefdevice appliedthereto. y

' "Referring to the drawings, 1v indicates I the lamp bulb, 2 thecasing, 3 the deflector .A and 4 the lens. The, glare preventing deviceconstituting my-invention is adapted to be mount-cd within-thelamp andbehind the lens, andgit comprises a series of thin fixed translucentplates or slats 5 of sc ft wood spaced apart vertically at equallntervals 'and' having their front edges bearing against or locatedadjacent to Athe lens and extending rearwardly from said lens at ansubstantially 28 to the upward angle, preferably lat an angle vof laneof the lens, and which slats extend rom a point naar Y the upper end ofthe lensto a point substantially opposite the center 'of the lamp bulb`and which have non-lustrous surfaces and are preferably made ofnon-metallic, lightabsorbing material. of wood in its natural stateunpohshed and unvarnished, and poplarl wood has been found to bethe mostsuitable for this pur- The slats are fixed on vertical suppose. portingbars 6, preferablyv by engagement with angular slats 7 formed lin thebars, in which the slats are held by glue; or other SpecificationofiLetters Patent.

These slats are made,

suitable means'of locking the slatsito the' barsin angular position maybe provided. Secured to the upper ends of the bars is a top'slat 8having its surface -lying in vel'ti cal planes and constituting asupporting member for the frame formed of the bars and slats. Secured tothis'upper support.- ing member by being clenched thereon or otherwiseengaged therewith,.is la hanger 9,' preferably consisting of. pliablemetal andadapted to be clamped between the lens 4; and the inwardlyturned flange of the cas? ing or shell 2, whereby the' frame isvertically suspended.
